    I own a Canon EOS 7D Mark II with a crop factor of 1.6 and mounted with an EF 100-400mm F/4.5-5.6L IS II USM. This gives me a lens of 160-640mm, and with the EF 1.4 III extender mounted between that it gives me a lens of 224-896mm. Which is perfect for shooting airshows, and any distance shots. (((( I originally bought an EF 2x III extender for this setup (and it gave me a lens of 320-1,280mm ) but it would NOT let me use the Auto Focus system (because it was above F/8 but I did not know this at the time), but I could still use the 2X in the manual mode with NO problems. )))) So I called Canon and they said that I needed the EF 1.4 III extender with this setup if I wanted to use the AF system of the 7D, because this would keep the F/ number below F/8. And Canon also said that the 2x III extender was better suited for any F/2.8 lens, because it would keep the F/ number below F/8.

    After renting 1.4x for a while, I decided to buy one. So glad to have it in my camera pack. Canon hands down makes the best glass and this extenders are a must have for any wild life photographer. I would highly recommend the CanonEF 1.4x III Extender it's so smooth and tack sharp.

    Excellent Canon accessory for their zoom, and telephoto, lenses. At f/2.8 little loss of fast aperture and f/22 increases to f/44 for greater depth of field. EXIF data says it makes 70-200mm equivalent to 422mm in 35mm-format (APS-C D-SLR).

    The Canon 1.4x teleconverter can help create excellent photos. Slight loss of maximum f/stop but also can obtain greater DOF (depth of field) at smallest f.stop. Keep lens surfaces clean or dust spot in photos.

    I've only used this in connection with a 100-400mm ver 2 Canon lens, but in this combination, the extender yields images that are very sharp as compared to this lens without the teleconverter. Excellent product

    Extender 1.4 works better than I expected with my Canon 100-400 L lens and Canon 7d MII. Going to try the 2.0 extender next.

    The extender is used in conjunction Canon 7D Mark II and 100-400 mm lens. It is used for outdoor/birding photography. The extender makes many otherwise hard to photograph images available.
